I haven't got it to hand now, but I did have the first edition Haynes manual for the first Sierra which I'm sure said ATF as the lubricant for the T9. But given the early 5 speed Sierras, of which I had one that did, had numerous problems with gear boxes going very noisy due to lubrication problems, Ford also changed the oil spec quite quickly to semi synth as well as certain component changes. Some mentioned in the article I linked too.
